ROLLING-MILL SHEABING AND FILING APPARATUS.

Specification of Letters Patent.

Application filed August 26, 1918, Serial No. 251,446. Renewed March 11, 1920. Serial No. 365,096.

To all whom it may concern:

Be it known that I, linrzny G. ()Buisx, residing at \Varren, in the county of Trumbull and State oi Ohio, a citizen of the United States, have invented or discovered certain new and useful Improvements in Rolling-Mill Shearing and Piling Apparatus, of which improvements the following is a specification.

My invention relates to machinery or upparatus useiil in rolling inills for cutting or shearing roller blanks into desired lengths The object tliei'eoljis to provide blank shear ing apparatus whereby elongate strips of metal may be quickly sheared to accurate dimensions with a minimuni amount of labor.

A further object of my invention is to provide an apparatus whereby. elongate blanks may, in a continuous operation, bi successively sheared and the sheared lengths properly and evenly piled.

1n the accompanying sheets of drawings,

which form part of my specifications, I have illustrated one embodiment of my invention. Figure 1 is a plan view of the general arrangenient of the apparatus; Fig. .2 a vertical sectional view to enlarged. scale taken on the line 1I ll Fig. 1; Fig. 3 a vertical sectional view to enlarged scale ol? the left end of the apparatus of Fig. 1, the plane of view being indicated by the line III-J11, Fig. 1; Fig. 4 a plan view of the left, end of the apparatus shown in Fig. 3; Figs. 5 and 6 sectional views taken. respectively, on the lines VV and \I--VI, Fig. 3; Fig. 7 a side view of the piler shown at the right end of Fig.1, the'plane of view bein indiouted by the line VII-VII. Fig. 1, lg. 8 a plan view of the piler; and Fig. 9 a detail sectional view taken on the line IX-IX, Fig. 7. l

In the practice of my invention, I provide a blank-cutting shear having a movable shear blade, and at the sides of such shear I arrange roll tables or other conveyors for feeding, an uncut or unsheared blank to the shear and for removin" the sheared lengths therefrom. Lying in t 1e path of the blank being sheared, means are provided for arresting the movement of tie blank after a predetermined length, of it has passed between the Shear blades; and, coordinated with the operation of the shears, means are provided for releasing the blank arresting means so that the cut length may he passed along and that the remaining uncut blank may be. advanced until the desired len th has again passed between the shear blaies. At the end of the roll table a piler is provided t'or reeeiving and piling the sections of the blanks as they are successively sheared.

Any suitable form of shear may be employed, its size and rharaeter iilepending somewhat upon the particular blanks it is intended to out. The shear illustrated herein is for cutting thin sheet metal, and. as shown particularly in Fig. (:oinpri. a housing 1 provided with a ris'lltlltnitll'zy' blade 2 and with a reciprocating head 3, to which there is attached a blade 4 adapted to cooperate with the blade 2. The reciprocation of the head 3 for moving the blade 4 may be offected. by the rotation of a. shaft 5 in the manner well understood. Norn'ially the reciprocating head 3 is inactive, and, to cause it to reciprocate, any desired ineeha insm, operated as by a treadle (3 (Fig. 1), may be provided.

At each side of the shear, conveyors are provided for moving a blank to and between the shear blades, and' for further passing to the pilereut lengths of the blank. The C011 veyer is preferably a live roll table consisting of a series bl rolls 7 adapted to be driven by a suitable motor 8 which is connected, through the illustrated train of ears and rotatable shaft 9, to each of the re ls.

Various means may be provided for arresting the advance of a blank after the desired length thereof has passed between the shear blades. such means depending somewhat upon the particular type of shear used for cutting the blanks. In the illustrative embodin'ient of my invention the movement of the blank is arrested by a gage 10, pivotally mounted. as at 11, to a carrier 12; which carrier is adjustably mounted upon a support 13 extendin above and in alinement with the roll tab 0. For securing the carrier 12 to the support 13 at. any desired distance from the shear blades, the support may be provided with a plurality of suitably spaced holes 14 adapted to receive a pin 14 extending through a hole in the gage carrier 12. Due to its own weight, the gage 10 normally rests either upon one of tie rolls Tor upon one of the short platform plates 15 arranged between adjacent mils.

' from the shear, may be Hence, -when the end of the blank being conveyed by the roll table strikes the age, the further movement of the blank wil be prevented. When the blank has thus been stopped, the operator presses the treadle 6 to cause the shear to ma (c a cut.

That the gage may be then raised to per mit the out section of the blank to be )assed beyond the gage, means, coiirdinate with the operation of the movable shear blade, are provided for moving the ga e, As shown herein, an arm 16 is secure pivot point 11 thereof. This arm is adapted to be pressed downwardly, and the gage 1 0 accordingly raised to the dotted line posi tion in which it is shown in Fi 3 b means of a finger 17, longitudinally s idab e u v on, but secured for rotation with, a rock s aft 18. As seen in Figs. 3 and 4, an am 1 9 projects laterally from the shaft 18 and is connected at its oiter end by means of a link 20 to a pivoted arm 21 provided with a roller adapted to rest upon a cum secured to the rotaiel-Jlc shaft 5. The con figuration of the cam 23 and its location upon the shaft 5 are such that, as the reciprocating head ,3 rises, the pivoted arm 21, will be lifted, and, through link 20 and arm 19, the shaft 18 will be rocked to depress the fin er 17 and hence liftthe gage 10.

11 case the ap aratus is use forrutting relatively thin s set metal, such asis eon:- templated by the particular apparatus shown herein, the several rolls 7 ma as particularly indicated in Fig. 5, be provided with annular grooves 24. lying in planes pcrpendicular to the axes of the rolls, and the lower face of the gage 10 may be provided with projections 25 adapted to rest in the rooves 24. With such arrangement, a thin sheet of metal cannot, hyslipping between the gage and a roll, advance beyond the gage before being cut.

The shear illustrated herein is of's'ntlicient width to simultaneously out several blanks fed side by side to 'the shear. fi o the end that the simultaneously sheared lengths may, while they are being conveyed from the shear by the roll table, be piled one on top'of the other, the rolls 7 beyond theend of the age support 1.3 have their outer ends tapere as indicated in Fig. l, and suitable lateral uicle or deflecting plates 75 are arranged etween the outer tapered ends of the rolls. H v

At the end of the roll table there is provided a piler and transfer table, so that the successively sheared lengths, as they are continuously passed along the roll table properly piled and uiekly removed from t .e vicinity of the s ear; The pile;- comprises a pair of-vertb cally disposed plates 26 having serrated lower edges adapted to rest upon the piling to the gage 10 and projects rearwardly from. the

rails 76 of a truck 27, movable, by means of the transfer table presently to be described,"

to and frorna position at the end of the roll table. The piler plates are lateral] adj'ustable to receive out blanks of di erent widths, and vertically movable to permit a loaded truck to be moved laterally below their lower'edges.

As shown herein, pairs of arms 28 and 28 .a chain 33, and to each screw a hand wheel 32 is attached. That the plates may be held in vertical alinement, they are connected to each other by two pairs of toggles-comprising laterally projecting linlrs 34 pivdted to the arms 2!? and 28, and vertical links 35 pivoted to the outer ends of the'li'nks 34, as indicated in Figs. 8 and 9.

For moving the piler plates vertically, the outer ends ot ihe screws 36 and 30" are suspended from yokes 37; and pivotally mounted on supportsprstandards 39 and 40, the yoke being cd'riiiected to the screw 30" by means of a link'36',fto permit a slight longitudinal movement of the plates 26 when the yolrcs swiu to more such plates vertically. Each yo re isprovided with a laterally projecting arm 41, which arms are connectcd to each other by a rod 42 so that the two 'js olres may swing in unison. The piler may be counterweighted h means of a weight'43 ndjustably carried by an arm 44 secured to the yoke 38.

As will be seen in Figs. 2 and 7, the general arrangement of the piling apparatus is such that the bed orsupporting rails 76 of the truck 2? is below the plane of the roll. table. the end of the roll table and upon the truck, there may 45 adapted I roll table. The pinch rolls will ordinarily To feed thesheared blanks beyondbe provided a-pair of pinch rolls to e driven by' the shaft 9 of the be driven at a speed suflicient to cause a blank, after it passes beyond their engage ment,'to slide upon the plate beneath its suilicient distance to clear the pinch rolls ,and their housing; That the ends of the' ustable stop 46 ,may be and is move is by atransfer table. seen in Figs. 2 and 3, the transfer table 77 rests within a shallow pit 47 upon a track 48' x-, tending at right angles to the roll tab e.

stub-end tracks 58, 59, (so and ill.

The transfer table is adapted to he moved from one to the othereud ol' the pit, and heiu'e l'roln one side to the other of the, roll table, by means of a motor ll), the driving conni retions between such motor and transfer table including a shaft 51), bevel pinions :31 and U2. counter shaft 53, pinion 5-1- and a rack :15 secured to the bottom of the transfer table. on top of the transfer table there are two truek-supporting tracks ms and 57, and leading from the opposite sides o'l' both ends of the pit 4-7, and parallel with the gem eral line of ext nt of the roll table, there are Thus, while one track is being loaded, a previously loaded truck may be mored from the transfer ta le and an empty truck placed on such table in readiness to be moved to loading, position. it will be seen that the arrangement o l' tracks lends itself to a rapid piling of the blanks and their qui k removal from the vicinity of the shear.

in the operation oi: my invention, the gage rarrier 12 is adjusted to such posi tion upon the support 13 that the stopping face of the gage W is at the exact required distance from the plane of operation of the shear blades 2, l to effect the cutting of a blank into the desired lengths. The gage carrier is held in its adjusted position by means of a pin 14 extending through such carrier and through. one of the holes 11; in the support 13. The motor 8 is preterahly driven continuously to drive, the rol s 7 of the roll table. Accordingly the blanks are. led by the roll table between the shear blades 2 and 4 until the end of the blanks strike the gage if), at which time the operator presses the treadle 6 which controls the insirumentalities for causing the reciprocating hep d 3 ol' the shear to descend and cut the blank. As the reciprocating head rises. the cam '23, secured to the shaft 5, Hits the arm 21, and. through link 2), arm 19. rock shalt l8 and finger 17, causes the gage 10 to he lifted so that the continuously rotating rolls 7 may convey the sheared blank to the piler. As the sheared blank passes beneath the gage, the gage is released so that it again falls to a position. for arresting the end of the uncut blank. Thus one blank after another may be continuously out.

At the end of the roll table the pinch rolls 45 engage the sheared blanks and cause then] to move beyond the end of the table upon the truck 27 between the piler plates 26. When the top of a pile is about; even. with the meeting plane of the pinch rolls '15, the piling plates 26 are raised by rocking the pivoted yokes 37 and 39, and the motor 49 is then driven to cause the transfer table 77 to move laterally until the truck 27 supporting the pile of plates is in alinement with either the tracks 58 and GI) or the tracks 59 and 61. In such position an unloaded truck will be beneath the iler plates 2i; and the loaded truck may be removed along one of the. tracks. If the loaded truck is' remored along the track 58, an unloaded truck may be placed on the transfer table 77 from the track 60, so that, when a second pile has been completed, the transfer table may be moved to the o posite end of the pit 47 for repeating t e operation of removing; a loaded truck alon the track 59 and. receiving an unloade truck trom the track 61.

As already explained, the plates 26 may be adjnstcii laterally to receive blanks of any desired width, such adjustment being effected by the rotation of the plate-supporting screws 30 and 30". justable stop 46 may be placed at the required distance from the pinch rolls 45 to cause the ends of the blanks to be arranged creniy in the truck.
